cos_sim_calc_boot allows boot strap analysis. This function should be used as argument for 'statistic' in the boot function of 'boot' package.
cos_sim_calc_boot(data, indices)
Arguments
data: Term Document Matrix generated from tdm_for_lsa function of this package. In this matrix, rows are terms and columns are abstracts.
indices: index of matrix.
Details
while calling this function we need to transpose the input tdm and can also set the number of replicates. boot package is required to call this function.
Returns
It will return a matrix containing the cosine similarity of pairs of terms in the abstracts. This object is in same format as returned by the 'boot' function of 'boot' package.

Examples
## Not run: test_boot = boot(data = t(nummatrix), statistic = cos_sim_calc_boot, R = 2)## here 'nummatrix' is a Term Document Matrix, boot inbuilt function of boot package, ## R is number of replicates here it is 2. User can extend this number.
